My computer shuts off unexpectedly

Specs: Windows 10, Huperx and corsair vengeance
My computer shuts off after awhile. The time varies. I thought it was the processor so i bought some new thermal paste but that didn't work. Then i thought it was the power supply fan but checked that and and it works. Then i thought it was a virus so i got my brothers old hard drive and pluged that in works fine but then it shut off again after awhile so im at my wits end noe. Help

Make sure the power supply is dust free.

Try an external fan on the power supply, if it is still shutting down, after cleaning.

I have checked to see if the power suply or the processor are heating ip but both were cool to the touch. So i started to feel around and i found the sorce of the heat but it is a part i do not know the name of. I have used ice packs to try and keep it cool and it greatly extended the time it could go but still shuts off before 2 hours.

Thanks for that info.

Once you are sure the power supply is Ok, remove all the extra stuff that is not needed to test, such as extra memory, in other words, test with only one stick installed.

Plug your monitor into the onboard video socket.

Does it shut-off & stay off or randomly restart? If you haven't already done so, disable the auto-restart feature:

Touching the processor is not how to check for overheating. Either install hardware monitoring software such as Asus AI Suite or check the temp readings in the BIOS. The CPU should be in the 30s at idle & under 60C under full load.

What you circled in the 1st pic is the motherboard chipset. It's unlikely to be the cause of your problem.
The 2nd pic shows that the case interior is somewhat dirty/dusty. It should be blown out with compressed air. One thing I noticed is that you have the RAM installed incorrectly. One stick should be in DIMM_A2, the other should be in DIMM_B2. This is explained in the manual on page 1-9:

As for you changing the thermal paste, it probably didn't have to be done. Paste does NOT go bad so unless you disturbed or removed the heatsink/fan for some reason, it should have been left untouched. Since you have a 970, you have an AMD CPU. All AMD CPUs use the middle dot method for paste application, so if you did it differently, you should remove the HS/F again, thoroughly remove ALL traces of paste from both the CPU & heatsink, & then reapply the paste correctly. Put a tiny dab in the center of the CPU, then install the HS/F. That's all there is to it.

Here's a pic of the paste:

It shuts off and stays off. 1 does the ram being installed imcorrectly have anything to do with it over heating? Because if not id rather just leave it. Less work. 2 i have checked the heat at the BIOS mode you can do at start up. I do not know how to check the temp when its in full load and its hard to look since i do not have a lot of time before it shuts off. Right now the temp is 47°c.
And now about 30m later its at 61°c still in the limbo not started up but not off state.

Use HWmonitor, to chedck temps etc. Also check you PSU, using 12,5,3 volt outputs

p.s. when was the last time your cleaned it for dust?
